As you probably know, the BBs added a meganism to the game, that should regulate the amount of money involved in BB. As we can only guess if this amount increases or decreases, the BBs have the exact numbers. Via the new salary adjusments the amount of money in the game will stay the same, or will show a small decrease in the long run if needed. So I think raising the subject again isn't really needed, since the meganism is there already and this will fix the whole problem, if there really is a problem.
You, me and many other 'more senior' managers joined the game in a time where prices were lower, players were far worse and daytrading was an extremely effective strategy to get to the top as fast as possible and training wasn't. I trained my big men for like 4 seasons, but then when I wanted to sell some, the price of capped allstar centers suddenly dropped to ~3m when potential was introduced. Training was useless.
Now the price of such a center is back to 4m, while it was over 8-10m at that time (check the history's of players like this one
(/player/2308283/history.aspx)). Would be awful if you wanted to sell your capped allstar center after 4 seasons of full training around may 2009, only getting 1,9m for such a great player.
While it is true that the starting teams probably can't improve their teams very fast via daytrading/the transferlist anymore right now, it is still possible (but a lot harder). They can, however, get a lot of value from training their players. Since all new teams stars with a few youngstars the need of being at the transferlist isn't huge. With lower prices it certainly is, and I think it's imbalanced again.
Also you talk about 'normal' players being sold for 5m now, but that's normal for you, for me, but not for starting teams. You can buy normal players for 100-200k for those teams.
The problem of inflation at the transferlist isn't a huge deal as well, and it only affects very few managers. Most of the managers sell and buy their players at about the same time. You sell you talents, buy new onces, you sell your top players and buy new top players. All in the same market conditions since the time between buying and selling isn't large. It might be a problem for managers saving money at the bank, when they sold their players in the 2m period instead of the 8m period, but that's a risk you take by saving.
